Explanation:
(1) Green plants are called autotrophs/autotrophic organisms since they synthesize their own food.
(2) The food synthesized by the plants is stored as Starch.
(3) In photosynthesis solar energy is captured by the pigment called Chlorophyll.
(4) During photosynthesis plants take in CO₂ & H₂O and release oxygen (O₂).
(5) Proteins contain nitrogen (in amino acids).
(6) Framers enrich the soil by adding green manures and fertilizers (rich in NPK.)
(7) In most green plants, photosynthesis takes place in the chloroplasts of leaves.
(8) Plants are unable to use atmospheric nitrogen (N₂).
(9) Green patches in stagnant water are aquatic algae.
(10) During photosynthesis, solar (heat) energy is captured by the leaves and stored as food.
(11) The occurrence of photosynthesis is tested by the presence of starch in the leaf.
(12) In lichens, fungi (mycobiont) and algae (phycobiont) live in symbiotic association.
(13) During photosynthesis solar energy (radiation) energy is converted into the chemical energy of food.
(14) Leguminous plants are examples of mutualism or symbiotic association.
(15) Legumes or leguminous plants have Rhizobium bacteria in their roots.
True/False:
i. The food(carbohydrate) synthesized by the plants is stored as starch. hence it is true(T).
ii. Plants take carbon dioxide from the atmosphere mainly through the minute pores- stomata present on the leaves. hence this statement is true (T).
iii. Solar energy is converted into chemical energy during photosynthesis. hence this statement is false (F).
iv. Carbon dioxide is utilized during photosynthesis, hence it is false (F).
v. The starch is also called the stored form carbohydrate. Hence true (T).
Very Short answer type questions
1. The green-coloured pigment present in the leaves of green plants is called chlorophylls.
2. The small, minute pores on the lower surface of a leaf are called stomata.
3. Insectivorous plants grow in soil which is deficient in nitrogen.
4. Plants which feed on the dead and decaying matter are saprobes or Saprophytes.
5. Type of nutrition found in Amarbel (Cuscuta) is parasitic (heterotrophic).
6. Special structure in Cuscuta (a parasitic plant) for absorbing readymade food from the host plant- haustoria.
7. Centrally located spherical structure in the cell is the nucleus.
8. Kidney-shaped cells which guard each stoma are called guard cells.
9. A jelly-like substance present between plasma membrane and nucleus is known as the cell fluid or cytoplasm.
10. The plant on which a parasitic plant climbs is known as its host plant.
11. A thin outer boundary with which a cell is enclosed is called a plasma membrane.
